Strange, I was wondering the same thing about mine too! Lol

No chargers have truly decent IR measuring ability.

Your hitting your marks on landing. Every once and awhile the bounce will get ya if your having a off day.

Well, I am not interested in all the "I am so perfect at landing" story tellers anyway.
The Mod is to help all the normal people flying this thing!
Don't do the Mod and one day you will regret it.....
(And I bet those 'perfect landers' have bounced aircraft plenty of times too anyway really!)

Little off topic here, I looked through all the different Freewing plane threads and this one's the most active. I bought a Freewing 90mm F-16 a year ago second hand. The plane was well maintained but the previous owner used some sort of clear coat that created a fair amount of yellowing and cracked the paint up something feirce!! Does anyone know how to strip the paint completely off without damaging the foam at all? It's the Thunderbirds scheme and I'm lookin to repaint her.

You could use acetone. Iíve done that method once but it takes a long time and that stuff is pretty nasty. I am never going to do it again.

Youíre probably better off just fixing any areas with spackle, sanding those areas and then painting straight over the old paint. I normally donít even use primer.

It’s difficult to remove the paint, but it’s real, because EPP, not afraid of active solvents, acetone and other solvents can be used, but it will be a dirty job ...
We wash off the paint first, then the remaining paint to a clean surface.
It will stink a lot, it is necessary to use respiratory and vision protection.
An exhaust device will help 50%

Acetone won't hurt the EPP foam? Interesting.

True. The thing though is, claiming that the nose gear spring needs to be modified in order to prevent bounce landings implies that the nose gear / aircraft has a design flaw. That is not the case what so ever. Without modifying I'm able to bring this aircraft to a landing super smooth. Even the landing on the maiden was nice and smooth. I have bounce landed this aircraft twice during the entire time I've flown it. First and second times were somewhere between the 6th and 12 flights. First bounce landing was because it was ever so slightly tail heavy (because of the 90mm upgrade I did to it). In that situation, sure, it was flyable and very good in the air. But as soon as I landed her, the aft portion of the a/c pulled itself down causing the nose wheel to come back up off the ground. This in turn caused the a/c to become airborne again, resulting in the bouncing three to four times. Second time I bounced it was because I came in so slowly, the a/c stalled about a foot off the runway and plunked down hard, again causing the a/c to bounce three or four times.

But doing this nose gear spring modification would not have prevented the a/c to bounce given these two situations that I put it in. This was because of pilot error, nothing more, nothing less. Had absolutely nothing to do with a nose gear spring, what so ever. And there are many other scenarios that can cause this a/c to bounce on landing as well. These are just the only two I myself experienced.

But the key is, I learned from the mistakes and now prevent the a/c from entering such situations. Once I was able to do that, problem solved.

And this A-10 isn't exactly the easiest for me to fly. I've flown an array of a/c, both prop, EDF, even nitro for years. The A-10 is easy on takeoff and flying. But landings are a totally different story for me. For me, landing this A-10 gives me the most stress out of all a/c I've landed. Not sure why that is. Mine is pretty heavy though, weighing in at a little over 15 pounds with batteries installed. Mine has brakes also, so that's another 3s battery included.

The a/c that is second on the stress level for me is the 90mm F-16, again, especially on the landings.

Yes, everybody has off days. But the one very important lesson I've learned is, if the landing doesn't feel right while coming in to the final approach, no worries, make a go around pass. For so many years I had this idea that I had to land on the first attempt. When I began to fly this A-10, I started to do go arounds if I didn't like the feeling of the approach. I've prevented lots of rough landings doing it that way. We all know what the feeling is like when the a/c is coming in just perfectly and we also know what it feels like when we have doubts about how the approach is going. I will only land if I am very comfortable with how the a/c is making it's final approach. So the key is to be able to 1)identify when the a/c is in such a scenario, and 2) successfully removing it from such a scenario. In my case, I do a go around pass. and do it again until it comes in the way I like it, the way it feels right. Works every time.

It will in specific situations. I used acetone to remove the factory paint from my first 90mm F-4 Phantom. I found that the foam becomes agitated and ultimately gators super bad if the acetone is rubbed back an fourth on the foam. Ideally, you want to just wipe it in one direction only and limit the foam's exposure to the acetone as much as possible. The longer the foam is exposed to the acetone, the more it will start to gator. Rubbing it back and fourth expedites the gatoring.

Fascinating. I have both the A-10 and 90mm F-16 and could not disagree more strongly with this statement. My A-10 has after 30 flights never had a bounced or bad landing. Some maybe werenít perfect, but the only plane thatís easier for me to land is my 85Ē E-Flite Cessna. I have the straight (non-trailing link) mains and nose.

Meanwhile, my F-16 has around 300 flights and still gets my full attention every landing. Granted Iím flying on a narrow and relatively short runway, which causes most of the problem, but I still celebrate every landing that I avoid going up on a wingtip with it. Granted thatís virtually all of my landings now when I donít have to fight a crosswind, but even a 5-10 mph crosswind makes me nervous with the F-16.

I think my situation is also flying site setup. We fly at a long narrow parking lot. This parking lot has 8 inch cement curbs on all edges, with some islands for bushes making areas of the runway even more narrow. There are also trees, shrubbery, and light poles along the runway. This A-10 is pretty heavy and takes lots of room for landings. I get pretty tied up and nervous landing her because of all this. Now if I were out where we didn't have such obstacles, especially the cement curbs, I'd probably feel a great deal more relaxed and comfortable.

The F-16 is much smaller, lighter and thus why I feel a bit less stressed when landing her there.

To give you an idea of the runway I'm flying from, here's a vid taken of flying my A-10 back when I was within my first 12 or so flights. Lots of stress with all this stuff. And with these curbs, I have to be right on the money when landing. Taking off and flying her around is fun and exciting, but I always don't look forward to the landings with this A-10 because of it's size, weight and the obstacles around where I fly her.
